﻿Natural Selection
Natural selection is the gradual process by which biological traits become either more or less common in a population. It is a basic mechanism of evolution. The term natural selection was promoted by Charles Darwin who intended it to be linked with artificial selection, what is now call selective breeding. Variation exists within all populations of organisms. This occurs partly because random mutations cause changes in the genetic makeup of a single organism. These...

﻿Natural selection
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.
Darwin's grand idea of evolution by natural selection is relatively simple but often misunderstood. To find out how it works, imagine a population of beetles:
1. There is variation in traits.
For example, some beetles are green and some are brown.
2. There is differential reproduction.
Since the environment can't support unlimited population growth, not all...

Natural selection is the gradual process by which biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution. The term "natural selection" was popularized by Charles Darwin who intended it to be compared with artificial selection, which is now called selective breeding.

﻿The Peppered Moth
Before the Industrial Revolution in England in the 1800s, the population of the Peppered Moth (Biston betularia ), was mostly a light color with dark spots which helped them blend in with England’s trees. The trees had dark trunks with light white colored lichen. Only a small percentage of dark colored moths existed in this population. The few dark colored moths were effortlessly picked out by birds and other visual predators because they were easily seen against the light...

Natural Selection, as defined, is the process by which traits become more or less common within a population due to the survival or reproductive abilities of their bearer. Natural Selection is a key component to evolution. Naturally, there is always variation between individuals of the same species. Basically, organisms may contain slightly different traits making them more or less suitable to their environment. Thus, some individuals survive and reproduce more successfully than others.

Most educated people in Europe and the Americas during the 19th century had heard of or been exposed to Charles Darwin and the concept of evolution. Although he did not invent the idea, he did carry out the necessary research to document that evolution occurred and then made the idea acceptable for scientists and the general public. This was not easy to do, as the idea of evolution was not widely accepted because of the views of the post-revolutionary France. These ideas were considered a...

Whether it is Lamarck's theory that evolution is driven by an innate
tendency towards greater complexity, Darwin's theory of natural selection, or
the belief that the evolution of plant and animal life is controlled by a higher

have proven that species evolve over time, but the unanswered questions are "
How?" and "Why?" The...

Natural and sexual selection
One of the first and central mechanisms proposed by Darwin during his life was that of "natural selection." Some may refer to this as "survival of the fittest," whereby species that produce offspring have been successful in doing so because they have produced random individual features which have lead them to live longer and pro-create offspring with the same inheritable desired features. Not all individuals will be able to reproduce, therefore only the fittest...

Charles Darwin revolutionized biology when he introduced The Origin of Species by Means of Natural Selection in 1859. Although Wallace had also came upon this revelation shortly before Origins was published, Darwin had long been in development of this theory. Wallace amicably relinquished the idea to Darwin, allowing him to become the first pioneer of evolution. Darwin was not driven to publish his finding, which he'd been collecting for several years before Wallace struck upon it, because he...

This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait.

The predators (you) will prey upon the population, with the...

Natural Selection Paper
Natural selection is considered one of the most important processes for a variety of species and the environment which allows the fittest organisms to produce offspring. To prevent a species from extinction, it is necessary for them to adapt to the surrounding environment. The species which have the ability to adapt to new surroundings will be able to pass their genes through reproduction. Within the process of natural selection, it is possible for the original genetic...

What exactly is evolution?
In biology, the theory of evolution doesn’t exactly tell us how life began on Earth, but tells us how life, once it came into existence, diversified into the many incredible forms we see now and in the fossil record. It also helps us make sense of the way in which modern creatures continue to adapt and change today.
In biology, evolution can be defined as: ‘Any change in the heritable traits (those are...

Once upon a time, God created a simulation video game based on evolution. It was a video game that gave the player (in this case God himself) many different ways on how to change the environment, along with other factors too. There were a type of species from the game’s selection of other species called Barbellus- which had an antennae and a fish tail. God decided to create a large number of these creatures that lived in the ocean of the video game. However, in this species’ early stages, both...

Thesis
In Charles Darwin’s “The Origin of Species” the reader is introduced to evolution by way of Natural Selection, Artificial Selection, and Sexual Selection. The process of evolution is seen in species that undergo changes over long periods of time by adapting characteristics which will better suit them to their environments. By utilizing a combination of both hypothetical imagery and scientific observation, Darwin has developed a persuasive argument intended to shed light on the origins of...

Molluscs and Natural Selection
The process of natural selection is one of the most cited reasons for the evolution of a species, and it was made famous by Charles Darwin’s famous observations of finches in the Galapagos Islands. It is believed to work by way of random mutations; random mutations occur, as it indicates, randomly and spontaneously in a population for a multitude of genetic reasons. Mutations help to create variation of different traits within a species, and they can be...

﻿ Charles Darwin was a famous scientist whose most famous studies were the evolution of man and all other creatures. Darwin realized that certain species became extinct because they were not both strong physically and mentally, and he explains his theory which is called natural selection, and later claimed the phrase “Survival of the fittest.” This phrase can be seen through war as well as the aftermath of a war. World War II proved that the strongest bodies and minds survived, and in England...

While he was on the voyage of the H.M.S. Beagle, a man named Charles Darwin viewed the relationship of plants and animals all over the world. He observed organisms on islands off the coast of South America and those on the mainland. His observations showed that these organisms were related, but not identical. This led Darwin into believing that over time, organisms must adapt to suit their environment. He explained his theories thoroughly in his book, On the Origin of Species by Means of...

Humans in technology environment are not very free from natural selection. According to Charles Darwin, natural selection acts only for the good of each organism, so since our very first human ancestors had no natural defenses, they would die from what is considered today an insignificant disease.

When I think of evolution, I tend to think in terms of a series of what I call happy accidents. A creature through a series of genetic mutations is born with an attribute which fits well with its habitat thus providing it with an advantage over others of its kind. This advantage in turn makes the creature hardier than its compatriots leading to increased chances for survival and, perhaps, better selection of mates. This uniquely equipped animal then breeds and its new trait is passed on to...

Eugenics: The Artificial Selection
In the 1800’s, well-known biologist, Charles Darwin enlightened us with his theory of evolution and natural selection. In short, natural selection states that random genetic changes transpire within an organism's genetic code, such changes are preserved because they are valuable for survival. Darwin’s ideas came from economics applied to biology. By the late 1800’s Francis Galton, Darwin’s cousin, had thoroughly studied...

What is the relationship between sexual selection and human reproductive behaviour?
Sexual selection is the complementary force in which humans (and animals) compete with each other in order to mate with the partner of their choice (the ones which poses the most adaptive traits) in order to pass on their genes, producing healthy offspring. There are two types of sexual selection: Intersexual selection is where there is competition between the sexes; females are choosey because they have...

There are many theories that try to explain relationships between sexual selection and human reproductive behaviour. Evolutionary theory is one such theory.
There are many different species in the world which, according to Darwin, all came from one source, e.g. a bacteria or organism. Within each species, natural variation occurs, therefore the individual beings within the specie look different from one another. These differences are caused by genetic makeup (50% from your mum, 50% from your...

Darwin suggested that species evolve through sexual selection which involves attracting the mate with the greatest fitness and at the same time maximizing the chances of being selected as ‘fit’ themselves. Fitness, in the context of the evolutionary theory, means the ability to reproduce and have offspring, making it more likely for them to pass on their genes to the next generation. To explain this, Darwin came up with the two processes:
Intra-sexual selection refers to the evolutionary...

Natural selection is Charles Darwin’s most famous theory; it states that evolutionary change comes from genetic variation in each generation and the survival of individuals with different combinations of these variable traits. Organisms with such characteristics that increase their probability of survival in their environment will endure and possess more opportunities to reproduce. Over time these traits are passed on to their offspring and proliferate through the population. Darwin’s...

In Callicles argument on the Superior Individual, Callicles reasoned that in nature as well as humanity the strong dominates the weak. Also known as Moral Realism, Callicles argument on the Superior Individual is in fact one of interest because it is often deemed true, regardless of the false fallacies that exist. It is often believed that in nature as well as in humanity, strength and weakness are viable factors in...

Analysis Questions:
Define Natural Selection?
Natural Selection is the process by which individuals with inherited characteristics well-suited to their environment leave more offspring on average than do individuals with adaptations less suited to the environment.
Define Adaptation?
Adaptation is an inherited characteristic that improves an organism’s ability ti survive and reproduce in a particular environment.
What adaptation did certain moths have that increased their fitness...

﻿Free Response #2
Both Lamarckism and Darwinism were theories of evolution rooted in the concept of adaptation and an organisms response to environmental changes, however they differed in the mechanisms of how it happens. Lamarckism is in support of a theory that organisms evolve by acquiring favorable characteristics in response to their environment and directly pass them onto their offspring. In addition, according to Lamarckism, genetic variation occurs in a favorable direction, meaning...

Hereditary vs. Hormones
In this essay I will compare and contrast the influence of hereditary and hormones reflection on human behavior. First I will talk about genetics, also referred to as heredity. Then I will speak on hormones. Also in this essay I will discuss the endocrine system, identification of hormones and the glands responsible for secreting them, and genetics, behavior...

“Yes, we are all individuals!”
Can evolutionary psychology explain individual differences in personality?
It is now a “rule” that “all human behavioural traits are heritable” (Turkeimer, 2000. cited in Pinker 2002). Pinker says that when psychologist Eric Turkheimer made this bold claim in 2000, he was encapsulating over 40 years of studies that overwhelmingly and robustly support this view, and only slightly exaggerating (Pinker 2002). Estimates of the mean heritability for the fundamental...

After reading Malthus’ view, Darwin then noticed that if more organisms are produced than the ones that can survive, then they probably compete for resources. Darwin named this the struggle for existence.
Darwin also knew that organisms had natural differences within their traits. He assumed that some of those are...

The Beak of the Finch Summary
The Beak of the Finch by Jonathan Weiner explores evolution through the most famous examples in history—the finches of the Galápagos Islands. Charles Darwin’s theory of natural selection and the process of evolution are applied directly to what scientists refer to as Darwin’s Finches. Weiner follows scientists Peter and Rosemary Grant as they study the finches in real time on the Galápagos. Years of previous work, study and data is...

Beren Robinson Field Study
The three-spine sticklebacks are one group of fish that inhabits lakes in the northern regions of North America, where lakes were formed after ice sheets that covered the region retreated. This group of fish has gone through a rapid period of speciation, with the species that inhabits the lakes of coastal British Columbia being the youngest species (Smith & Smith, 2009). Beren Robinson of the University of Guelph...

Coevolution, Competition and Biodiversity are all different words, but have many things in common. All the words involve animals interacting with each other. In my first paragraph I will explain what coevolution is and how it makes the animals interactions change in species. My second paragraph is the description about the role of competition and how it ship and shapes natures' ecosystem. And last but not least, my third paragraph and it will be about the explanations of biodiversity and why...

﻿Discuss evolutionary explanations of group display in humans
From an evolutionary perspective, it has been emphasized that Natural selection has favored genes that cause group member to be altruistic toward members of their own group, but intolerant towards outsiders. This is known as Xenophobia-a fear and hatred of strangers or foreigners.
MacDonald suggests that over exaggerating the stereotypes of outsiders helps survival as seeing an exaggerated threat is safer than under estimating a...

Experiment 8.1
Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to...

Introduction to Biology, Lesson 3 Essay Questions:
Compare and contrast directional selection and disruptive selection, and provide an example of each.
Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to move in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white, pink, or...

The different genetic variation between plants and animals
Aim: to see the similarities between the different breed in a species
Genetic variation is what allows natural section and more importantly new alleles (a number of alternate forms of the genetic pool) to enter the population.
By having different genetic combinations, those of a population reveal different traits which may or may not be to their benefit, in respects to their social and environmental interactions or surroundings....

In 1864, the theory of evolution became very well-known when Charles Darwin published On the Origin of Species. Here he explained about his belief in what he called natural selection. Years later, after reading all about natural selection and becoming quite intrigued by it, a man by the name of Herbert Spencer, a polymath philosopher, came up with a synonym phrase for natural selection: “survival...
